Hello: I am currently losing a lot of hair - shedding actually!, Female, 65 no health problems, petite. have been considering taking Biotin tabs, in addition to correcting my diet, but have no idea what the actual dosage should be. I ve seen bottles of 10,000 mcgs, and not being a pill taker ordinarily, I wonder if tha t s too much. I do have a doc appointment (to get iron and thyroid checked) but that s several weeks away. any advice?? Thanks so much!
